Question

what is psuedohalogens​

Answer 1

Answer:

Pseudohalogens are groups formed by combination of two or more P block elements (in the periodic table) with a unit negative charge e.g. CN- (CN Minus) cyanide group a combination of carbon and nitrogen with uni-negative charge. They are called pseudohalogens as they form covalent compounds, complexes similar to the halogens, the 17th group elements in the periodic table. They differ from halogens as they are able to polymerise unlike halogens and their complexes are not paramagnetic.
